Objective Endometrial polyps are localised growths of endometrial tissue containing glands, stroma and blood vessels, covered with epithelium. The reported prevalence of endometrial polyps is dependent upon the population being studied and the uterine imaging technique utilised. The light microscopy literature provides very little information regarding their microvasculature and lymphatic syste...

The endometrial blood vessels form a vascular bed with a number of unusual properties. Unlike most adult vasculature these blood vessels undergo constant cycles of growth and regression during the reproductive life of the female. This short review covers a number of different aspects relating to endometrial vascular structure and function during endometrial growth, implantation, endometrial reg...

(i) What are the chief lesions associated with vascularization of the cornea ? (ii) To what extent do the various modes of vascularization facilitate a differentia! diagnosis ? (iii) Is there a demonstrable factor common to the lesions concerned ? (iv) What is the real significance of these adventitious vessels ? (v) Does experimental work throw any light upon the problem ? (vi) Is it possible ...

OBJECTIVE Measurement of microvascularization and determination of its prognostic significance in cases of lung cancer. METHODS Section prepared from histological material from 432 radically operated non-small cell lung cancer patients were stained with antibodies against factor VIII-associated antigen. During computer imaging, the absolute and relative parameters of the vascularization were ...

High-frequency volumetric Power Doppler ultrasound (HF-VPDU) captures flow-dependent signals in blood vessels and can be used to assess antiangiogenic therapy effects in rodent tumors. However, the sensitivity is limited to vessels larger than capillaries. Contrast-enhanced HF-VPDU reveals all perfused vessels by assessing stimulated acoustic emissions from disintegrating microbubbles. Thus, we...

background: endometriosis is the presence of endometrial glandular and stromal cells outside of the uterine cavity. our previous study showed that in vitro culture of human endometrial tissue in a three-dimensional (3d) fibrin matrix could mimic the early stages of endometriosis with invasion gland and stroma formation and sprouting of new vessels. objective: the objective of the present study ...

Neovascularization is defined as formation of new vessels from vascular endothelial cells derived from existing blood vessels. These new immature vessels are friable. They have increased permeability, lack structural integrity, and can result in lipid deposition and corneal opacities. Ultrastructurally, corneal neovascularization is characterized by vessels encroaching through separated stromal...

BACKGROUND Information about lymphatics and lymphangiogenesis in the human endometrium is limited. We investigated the distribution of endometrial lymphatic vessels during the normal menstrual cycle and in association with endometrial adenocarcinoma and investigated the expression of lymphangiogenic growth factors, vascular endothelial growth factor (VEGF)-C, VEGF-D and VEGF receptor-3 (VEGF-R3...

Purpose: Adipose tissue contains a population of tumor-tropic mesenchymal progenitors, termed adipose stromal cells (ASC), which engraft in neighboring tumors to form supportive tumor stroma.We hypothesized that intra-abdominal visceral adipose tissue may contain a uniquely tumor-promoting population of ASC to account for the relationship between excess visceral adipose tissue and mortality of ...
